Women and men, in comparison to other clusters, presented lower overall serum concentrations of DhCer; specifically, Cer(d18:0/16:0), Cer(d18:0/18:0), Cer(d18:0/20:0), Cer(d18:0/22:0), suggesting a decrease of de novo hepatic ceramide synthesis, which has been associated with reduced steatosis. This evidence concerns the gene CBLN1 and steatosis.
